Good Energy has committed to freezing electricity prices until at least 2012.

The supplier, that supplies to around 26,000 people in the UK, have pledged to a price freeze on electricity tariffs.

Good Energy‘s electricity tariff has not risen since August 2008, a contrast to the high price increases by three of the ‘big six’ already this year.

The supplier did raise its gas prices however, up by 9.4% from September 6, due to wholesale gas price rises.

The gas price rise from September will be the company’s first increase since it started supplying gas in November 2008.

“We’ve been able to hold our prices, partly due to improvements in our weather forecasting techniques, enhancing our ability to trade renewable electricity more efficiently, and due to the investments we’ve made in developing new sources of green energy, such as our wind farm in Cornwall,” said founder and chief executive of Good Energy, Juliet Davenport.

Good Energy, Britain’s only 100 percent renewable power supplier, sources electricity from over 1,500 independent producers.
